Okay, apart from the bleeding obvious resemblances between MJ and DD, "Dave Dave" stumbles on his words twice: when saying "become my own person" and "stigmatized". Michael stumbled on his words exactly the same way. Example, the 1993 Oprah interview: he says referring to watching James Brown: "I used to get angry at the cameraman" and stumbles on the word "angry". Watch it closely, DD and MJ both stumble on words in exactly the same way. I am sure there's other examples of how MJ does this.
Also when 'DD' says "my favourite video game was Pole Position. And I was playing Pole Position..." Take note of the way he repeats "Pole Position". This is exactly what MJ did, I think an example was in Living with Michael Jackson and he is telling the story of Tatum O'Neill and he says "she told me to lay on the bed, and I layed on the bed..." and also when he says about Prince's birth he says "the doctor told me to pull him out, so I pull him out..." Notice the repetition? I am fairly sure there are clearer examples of this which I will try to find but the way DD repeats "Pole Position" really reminded me of exactly how MJ speaks.
